ABRAIJING APPARATUS.

'lfatented they a, ionic Application filed December 31, 1909. Serial No.5353M.

To all whom it may concern: c

it known that 'l, GlUSTAV A. Hassnn, a resident of Melfeesport, in thecounty of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in 'ltbrading Apparatus, of which the followingis a specification. 1

My invention relates to a new and iniproved abrading apparatus and anobject of the present invention is, to provide an apparatus of thisclass comprising a selfcontained, suspended or swinging structuredesired distance from be suspended at any the ground or floor andcapable of being moved at will either in a straight or a curved path. I

in the accompanying drawing, which illustrates an application of myinvention, Figure 1, is ing apparatus; embodying my invention; Fig. 2, apart elcvational and a part longitudinal sectional view; Figs. 3 and 4;vertical sectional views respectively taken on line lll llll and line Il-IV of Fig. 2; and Fig. 5 a part eievatioinil, and a part sectionalview, the section being taken on line VV of Fig. 2.

Referring to the drawing, 1 designates a frame preferably formed as anintegral caststeelstructure comprisinga bed-plate 2, a vertical member 3having a horizontaliled e 4-, a strengthening member 5, an outward lprojecting horizontal shelf 6 having a bcaring nieinl'ier 7, and astrengthening webg extending from member 7 and under the shelf 3 to thevertical member or device adapted ,to

While' l have shown simple and convenient frame this frame may bedifferently constructed. Mounted on and movable with frame 1 is a motor,as illustrated and as preferred, an electric motor, although the motormay be of a different type. This motor 9 having its shaft 10 coupledwith an end of a driven shaft 11 by means of a suitable coupling 12.

Shaft ll which is inclosed in a suitable casing 13, projects outwardlyfrom the frame and has mounted on an end thereof between a collar i land a nut 15 an abradinga wheel 16. "Wheel i6 is partially inclosed by astrong safety shield or hood l7 and se-- cured to said hood areoperating handles 18. llood l? is preferably of the form shown and isadjustably secured to a flanged sleeve 19 by bolts 2% passgd lhrough theflanged portion of, the aieeve. and the slots ill a perspective view ofan abrad formed in the back of the'hood, In Fig. 5,

the dotted lines indicate how the hand may be shifted when so desired. 1

The abrading apparatus is designed to he siispended from example, achain 22, at any desired'height. The supporting means and the apparatusare connected by a universal joint connec tion comprising in theconstruction shown, a saddle member consisting of a base 23" cured. tothe shelf 6 by bolts 24, and two uprights 25. Extending into the saddleand pivotally secured to the uprights thereof by a pin or shaft 26 is a.connecting member 27. Member 27 in turn is end of an eye-bolt 28 bymeans of a collar 29. This construction provides a simple universaljoint or coupling permitting the apparatus to be readily moved at Willin any direction:

The parts of the hpparatus are so proportioned thathenthe apparatus issuspended, as shown, it is a substantially balanced struc-. 'ture andmay be easily moved to bring the,

position,

What I claim is:

1. An 'abrad'ng apparatus comprising a suspended frame, means forsupporting the k driven shaft eoiipled with the motor shaft, anabradin'g wheel mounted on the driven shaft, and a universiil'jointconnection between the frame and the supporting means.

2. A suspended ab prising aframe, a motor mounted on the frame, onineased' driven shaft coupled with the motor shaft and projecting fromthe frame; an abrading wheel carried on the paratus, a universal jointconnection betweenthe frame and the supporting means, and a hoodprovided with an operating handle. 3. A suspended and substantiallybulanced abradiug uppuralus comprising frame, a motor mounted on theframe, a

driven shaft coupled with the niothr shaft, an abrading wheel carried onthe end of the driven shaft, means for supporting the apparatus, arid abetween the frame and 'the supporting means comprising an uprightn'ieinber, a depending member pivotally connected with ing member andsupporting means.

a suitable support as, for

secured to the lower 79 abrading' wheel intothe desired operative soframe, a motor mounted on the frame, e385" ading apparatus coindrivenshaft, means for supporting the up universal joint connection theupright, and a rod between the depcud 1 0 prislng a led with the motorshaft and projectingrom the frame, an abrading wheel mounted on an endof the shaft, an adjustable hood for the abrading wheel provided with anoperating handle, means for supporting the apparatus and a universaljoint connection between the frame and the supporting 1 means.

In testimony whereof I afiix my signature in presence of two witnesses.
